### レスポンス結果

クライアントが`http://example.com/items/foo`（`item_id` `"foo"`）をリクエストすると、HTTPステータスコードが200で、以下のJSONレスポンスが返されます:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

しかし、クライアントが`http://example.com/items/bar`（存在しない`item_id` `"bar"`）をリクエストした場合、HTTPステータスコード404（"not found"エラー）と以下のJSONレスポンスが返されます:

```JSON
{
  "detail": "Item not found"
}
```
